She was quoted saying it was her "sincere wish" that Camilla would have the title.
The Queen is the first British monarch to celebrate a Platinum Jubilee.
She also expressed her thanks to the public and her family for their support.
"And when, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support that you have given me, and it is my sincere wish that, when the time comes, Camilla will be known as Queen Consort as she continues her own royal service," she said.
Queen Elizabeth is spending her day privately on the Sandringham estate, with national celebrations to be held in June.
The Queen's reign began when she was 25-years old, following the death of her father, George VI, on Feb 6, 1952.
The monarch said that, 70 years on, the day is one which she remembers "as much for the death of my father, King George VI, as for the start of my reign".
Buckingham Palace earlier this year published a list of celebratory events planned for the summer which includes concerts, special ceremonies, street parties and an extra bank holiday for the public.
